METALLIC RAILWAY TIE.

Application filed June 21,

This invention re ates to a metallic railway tie, and has for one of its objects to provide a novel device 01 this character which will be light in weight and exceptionally strong and durable and capable of being manufactured and sold at a comparatively low cost.

lVith the foregoing and other objects in view, the nature of which will appear as the description proceeds, the invention consists in the construction, combination and arrangement of parts hereinafter fully described andclaimed, and illustrated in the accompanying drawing, wherein:

Figure 1 is a top plan view of the tie with the rails secured thereto, one of the rails being partly in horizontal section,

Figure 2 is a View in side elevation of the tie with the rails in vertical section,

Figure 3 is a sectional View taken on the vertical plane indicated by the line 33 of Figure 1,

Figure 4 is a sectional view taken on the vertical plane indicated by the line 44 of Figure 1,

Figure 5 is a sectional view taken on the vertical plane indicated by the line 55 of Figure 1, and

Figure 6 is a sectional view taken on the vertical plane indicated by the line 66 of Figure 1.

The tie comprises a metal casing 1 which is closed at its ends and provided with openings forming transverse recesses 2 and in terior longitudinal webs 3. The recesses 2 extend through the top wall and through the upper portions of the side walls of the easing 1. The webs 3 extend from the top to the bottom wall of the casing 1, and are located centrally between the side walls of the casing. The webs 3 extend in opposite directions beyond the recesses 2, and are provided with recesses 4 which are arranged in alinement with the recesses 2. Flanges 5 extend downwardly from the side walls of the recesses 2 and from one side wall of the casing 1 to the other side wall thereof, and they contact with the bottom and end walls of the recesses 4. The tie may be cast or made from sheet metal. lVhen made from sheet metal, the margins of the sheet metal blank will be welded together and the webs 3 will be welded to the top and bottom walls and flanges 5 of the casing 1.

Plates 6 and 7 are arranged in the recesses 2 and 4 and rest upon the side walls of the 1928. Serial No. 287,111.

casing 1 and upon the webs 3 to which parts they are welded. The plates 6 and 7 are positioned between the flanges 5 and welded to such parts. The plates 6 and 7 extend beyond 'the side walls of the casing 1, the former being provided with laterally extending lugs 8 contacting with the outer surfaces of said Walls, and the latter being of uniform width throughout; Certain of the lugs 8 are provided with bolt receiving openings 9, and the plate 7 is provided with bolt recelving openings 10, the openings 9 being elongated in the direction of the length of the casing 1 and the openings 10 being elongated in the direction of the width of the casing. Wooden blocks 11 and 12 are arranged in the recesses 2 and 4 upon the plates 6 and 7, and each block is similar in contour to the plate upon which it rests and provided with openings corresponding to the openings 9 and 10, respectively. The blocks 11 and 12 provide elastic cushions orrests for the rails 13 and 14, the rail 13 being secured in place by clamps 15 and bolts 16, and the rail 14 being secured in place by bolts 17. The clamps 15 contact with the base of the rail 13, and the bolts 17 pass through the base of the rail 14.

As the ends of the casing 1 are closed, and

as the recesses 2 are closed by the flanges 5 and the plates 6 and 7, water cannot enter the tie. The webs 3 materially strengthen and reenforce the tie, and also support the plates 6 and 7 at their transverse centers. By providing for adjusting the clamps 15 transversely of the track through the provision of the elongated openings 9 it will be apparent that adjustment of rail 13 relatively to rail 14 may be readily elfected to bring the rails to correct gauge due to wear or other cause. The slip engagement of the clamps 15 with rail 13 and movement of the bolts 17 in the slotted openings 10 admit of movement of the rails longitudinally in expansion and contraction.

It should be understood that the drawing is merely illustrative and does not pretend to give exact proportions. Furthermore, the said drawing is illustrative of a preferred construction, it being my expectation that various changes and modifications may be made without departing from the spirit and scope or my invention.

lVhat is claimed is 1. A tie comprising a casing closed at its ends and provided in its upper side with openings forming transverse recesses, flanges extending downwardly from the top wall of the casing at the sides of the recesses and from one to the other side wall of the casing, and plates arranged in the recesses upon the side walls and in contact with the flanges.

2. A tie comprising a casing closed at its ends and provided in its upper side with openings forming transverse recesses, flanges extending downwardly from the top wall of the casing at the sides of the recesses and from one to the other side wall of the casing, plates arranged in the recesses upon the side walls and in contact with the flanges, and webs arranged within the casing and extending longitudinally thereof, the webs being positioned centrally between the side walls of the casing and connected with the top and bottom walls thereof and provided with recesses for the reception of the plates and flanges.

3. A tie comprising a casing provided in its upper side with transverse recesses, plates arranged in the recesses and extending beyond the side walls of the casing, one of the plates being provided with transversely elongated and the other with longitudinally elongated bolt receiving openings, and cushion bloc-ks arranged within the recesses upon the plates.

4. A tie provided in its upper side with transverse recesses, and plates arranged within the recesses, one of the plates being provided with transversely elongated and the other with longitudinally elongated bolt receiving recesses.

In testimony whereof I afiix my signature.
